I bought it for trial because the unit price per piece was cheap. Recently I was using a monotaro brand "Abrasive cloth disk · alumina" yellow-colored guy, I thought it was okay but it is harder to bake this trussco compared to it, feeling that autogenous action is faster It was. Other than that I did not feel any difference. Because the unit price is about 110 yen per piece, I will try using this for a while.
